Trucking is a job where drivers put their health on the road. This isn’t just true for the obvious hazards of crazy truck drivers and dangerous detours. One often-overlooked health risk is the heat.

Dehydration, exhaustion, and overheating are all serious issues that truck drivers must avoid during the sweltering summer months. Here are our top 7 tips for drivers to stay cool and stay healthy.

1. Hydration: Even during the cooler months, many people don’t drink enough water. During the summer, this problem can turn deadly. Especially if you face dehydration while far away from the nearest truck stop and must concentrate on the road. Throughout the day, make sure to drink a lot of water—at least 64 ounces should be the goal. Fill up your vacuum bottle at a truck stop and keep your drink cool.

2. Use Air Conditioning: Make sure the air conditioning (A/C) equipment on your truck is in good operating order. Maintain optimal performance by checking and cleaning filters on a regular basis. Before continuing to drive during breaks, start up your truck and allow the A/C to cool the cabin.

3. Route Planning: If possible, try to schedule your travel to avoid the warmest hours of the day. Take stops in shaded areas to cool off and minimize exposure to direct sunlight if you must drive during the hottest times of the day. Always keep an eye on the weather and predicted temperatures for your route.

4. Dress Appropriately: Avoid getting a burn on your “trucker’s arm” by wearing long sleeves. Wear breathable or moisture-wicking materials. Make sure to pack sunglasses to keep your eyes healthy as well.

5. Cooling Accessories: Pack accessories to keep in a cooler that can quickly restore your body temperature. Gel packs, cooling cloths, fans, etc. If you feel yourself overheating, even in the A/C, pull over, take a break, and use these items to cool off. Use sunscreen every day, even if you are technically “inside” the cabin.

6. Night Tips: When parking, make sure to cover your windows and windshield. Parking behind trees or in the shade will keep the cabin cooler as well. If the air conditioning in your truck is insufficient, use fans or portable cooling equipment.

7. Track Your Health: Pay close attention to how you feel while driving and while resting. Monitor your health closely, both for your own safety and the drivers around you. Recognize heat-related ailments, such as heat stroke and exhaustion. Headache, nausea, dizziness, and confusion are among the symptoms. Seek cover, take a nap, and drink plenty of water right away if you encounter any of these symptoms.
